Class LongStaticHistogram

java.lang.Object

de.lmu.ifi.dbs.elki.utilities.datastructures.histogram.AbstractStaticHistogram

de.lmu.ifi.dbs.elki.utilities.datastructures.histogram.LongStaticHistogram

All Implemented Interfaces:

Histogram, LongHistogram

Direct Known Subclasses:

LongDynamicHistogram

public class LongStaticHistogram
extends AbstractStaticHistogram
implements LongHistogram

Histogram class storing long values. The histogram will start with "bin" bins, but it can grow dynamically to the left and right.
